2. Low phase noise voltage controlled micro- and millimeter wave oscillators
Sammanfattning : .... LÄS MER
3. MMIC-based Low Phase Noise Millimetre-wave Signal Source Design
Sammanfattning : Wireless technology for future communication systems has been continuously evolving to meet society’s increasing demand on network capacity. The millimetre-wave frequency band has a large amount of bandwidth available, which is a key factor in enabling the capability of carrying higher data rates. LÄS MER
4. Millimetre wave waveguide enclosed grid frequency multipliers and imaging
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
5. Compact and Efficient Millimetre-Wave Circuits for Wideband Applications
Sammanfattning : Radio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. LÄS MER
